Next, the operation of the embodiment of the present invention will be described. The combine starts the engine and drives the rotating parts of the machine body to move forward in the field to start the mowing and threshing work. Then, the grain culm in the field is the traveling car body 1
Mowed by the mowing pretreatment device 9 in the front part of the car, transported to the upper rear part and inherited by the feed chain 15,
The root of the stock is conveyed while being held, and the tip portion is supplied to the handling room 3. In this way, the grain culms supplied to the handling chamber 3 are subjected to the threshing process by the action of the handling barrel 10 which is rotationally driven, and the shed grains leak from the sorting net 16 to the sorting chamber 5 below. A part is carried around to the handling cylinder 10 and further transferred to the rear while undergoing the shredding process. Then, the grain-removed grains are separately sent to those that reach the dust outlet and fall into the sorting chamber 5 and those that are supplied to the dust treatment chamber 14.

At this time, in the sorting chamber 5, the swing sorting shelf 6 is swingably supported by the guide rollers 24 whose front portion is fitted to the guide rail 25, and eccentric at the rear portion. It is rocked by the reciprocating motion transmitted from the shaft 27 through the rocking arm 26. Further, below that, the sorting wind blown by the rotary driven compressed air slag 17 is blown out toward the dust discharge port 4.

The objects to be sorted, which have fallen from the handling chamber 3 to the sorting chamber 5, reach the swinging sorting rack 6 which is repeatedly swinging, and are transferred from the transfer rack 20 to the chaff sheave 21 side, and also have a wind sorting action. After being added, they are further sorted, and sorted into the first, second, and waste products. The first product sorted in this manner is collected by the first transfer spiral 18 and transported to the outside of the machine, supplied to the Glen tank 32 and stored therein, and the second product is collected by the second transfer spiral 19. The second grain raising device 33
Is supplied to the No. 2 processing chamber 12 to be subjected to the fried action. Then, a part of the dust is sucked by the suction dust collector 37 and discharged to the outside of the machine, and the rest is discharged from the tip of the straw rack 23 to the outside of the machine through the dust discharge port 4.

Further, the objects to be sorted which have fallen from the second processing chamber 12 or the dust processing chamber 14 into the sorting chamber 5 are subjected to the swinging action and the wind sorting action in the same manner as described above to be sorted. During such a mowing and threshing operation, the hydraulic mechanism mounted on the combine is operated based on an operation from the driver's seat or a control signal from the control device, and each switching valve 35 in the valve case 36 is appropriately switched. It is operated and each part is operating.

Next, a case will be described in which the cutting and threshing work is performed as described above, and maintenance such as inspection and cleaning of each part is performed after completion. First, in order to take out the swinging sorting rack 6 from the sorting chamber 5 to the outside of the machine, first, a screw 29 is removed using a tool so that the swinging arm 26 can be separated from the mounting metal 28 of the eccentric shaft 27 and pulled out. To The rocking sorting shelf 6 can be comparatively easily taken out by pulling it out of the machine from the dust outlet 4 side. Especially, during the pulling out work, the rocking sorting shelf 6 is temporarily used by using the support stand 7. Since 6 can be placed on top, it can be done easily.

After the inspection and cleaning of the rocking sorting shelf 6 are completed, the swing sorting shelf 6 is inserted into the sorting chamber 5 from the dust outlet 4 and mounted in the original state. At this time, the support base 7 is also used. The insertion operation can be done while doing so, and the work can be performed easily.
